China is getting really good at assembly robots too.
However if the process can be completely automated then why not do the manufacturing right where the bulk of consumption is going to happen to reduce shipping costs which are always growing.
That's a good point, but we still need to reach that outcome, and this will happen graudally. Whatever the end results of robofactory revolution, it will have to start here, in the factory of the world, because that's where we make robots for cheap.
